[0037] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments. At the same time, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0038] Referring to the attached Figure 1 , this embodiment provides a collaborative scheduling control method for a weeding machine in a field environment, including the following steps:
[0039] S1. Use a drone equipped with a high-definition camera, a multispectral sensor, and various related sensors and other monitoring devices to collect field and weed control-related information and preprocess the data, establish a neural network model for evaluating the priority of weed control operations, and output the priority evaluation results of weed control operations.
[0040] Use a drone equipped with a high-definition camera and a multispectral sensor to conduct an all-round scan of the field to obtain topographical information, crop distribution information, and weed distribution information of the field; among them, the high-definition camera is used to take visible light images of the field, and the distribution positions of crops and weeds are identified through image analysis; the multispectral sensor is used to collect spectral data in different bands, and according to the differences in the reflection characteristics of crops and weeds in different spectral bands, more accurately determine the distribution range and density of weeds. At the same time, use various related sensors to obtain meteorological data, soil data, weed control machine working data, vegetation index data, crop growth data, etc., to provide data support for subsequent modeling and analysis, thereby improving the production efficiency of weed control.
[0041] At the same time, transmit the collected image and spectral data to the ground control center. The ground control center uses geographic information system (GIS) technology to process and analyze the data to generate a three-dimensional terrain model, a crop distribution map, and a weed density distribution map of the field. Then, preprocess the obtained field-related information using existing technologies, establish a neural network model for evaluating the priority of weed control operations, input the preprocessed field-related images and other relevant information such as the field soil and vegetation into the neural network model for evaluating the priority of weed control operations, and finally output the corresponding priority evaluation results of weed control operations through deep learning.
[0042] The neural network model for evaluating the priority of weed control operations includes an input layer, a convolutional layer, a dynamic analysis layer, a fully connected layer, a comprehensive evaluation layer, and an output layer. Set the input of the neural network model for evaluating the priority of weed control operations as Among them, represents the preprocessed field-related image information, represents the preprocessed other relevant data information of the field, The convolutional layer performs a convolutional operation on the preprocessed field-related image information to obtain the feature vector of the field-related image. The specific process is as follows:
[0043] Among them, represents the feature vector of the field-related image; represents the convolutional function; represents the weight value; represents the bias of the convolutional layer; transfer the image features extracted by the convolutional layer to the dynamic analysis layer, and further dynamically analyze the field situation in the dynamic analysis layer. The specific process is as follows:
[0044] Among them, represents the output of the dynamic analysis layer, indicating the analysis result of the large field image during the time period; represents the state of the large field image in the time period before the start of recording; represents the sensitivity of the th feature; represents the standard reference value of the th feature; represents the weight value at different times affected by the climate; represents the projection conversion parameter; represents the element value at the vegetation index index location in the th area at ; represents the gradient amplitude at the vegetation index location segmentation in the th area during the time period; represents the error coefficient;
[0045] In the comprehensive evaluation layer, combining the results of the dynamic analysis layer and other relevant data information of the preprocessed field to comprehensively evaluate the priority of the large field weeding block, the specific process is as follows:
[0046] Among them, represents the output result of the comprehensive evaluation layer; represents the soil nutrient content; represents the proportionality coefficient, indicating the influence of soil nutrient changes on weed growth state changes; represents the vegetation or crop coverage rate; represents the time correction factor, used to adjust the changes in other relevant data information of the field over time; represents the sensitivity coefficient; represents the amplification coefficient, which amplifies the influence of the analysis result of the large field image on the comprehensive evaluation process; represents the weighting coefficient of sunlight on the comprehensive evaluation process; represents the sunlight intensity.
[0047] Then it enters the fully connected layer and the Softmax function. The fully connected layer outputs the evaluation result of the large field situation, and finally the output layer outputs the overall weeding priority evaluation result, and the output result is . In the embodiments of the present invention, for the large field blocks with priority weeding operations evaluated , its corresponding output is . After passing through the Softmax function, the confidence of the large field blocks for weeding operations can be expressed as:
[0048] Wherein, represents the number of large field blocks that need to perform weeding operations; represents the traversal variable.
[0049] Then, the error is calculated through the loss function, and the parameters in the neural network for evaluating the priority of weeding operations are optimized through gradient descent, and a neural network model for accurately evaluating the priority of weeding operations is trained.
[0050] By establishing a neural network model for evaluating the priority of weeding operations in the present invention, the control system can evaluate the priority of weeding operations according to the collected data, which helps to determine which areas need to be weeded first, improves the operation efficiency and effect, realizes intelligent scheduling, and maximizes the weeding efficiency; precise monitoring is carried out according to the evaluation results of the operation priority, effectively reducing the repetitive labor and resource waste in agricultural operations, helping the large field manager to reduce costs, improve production efficiency, and providing data support for the subsequent control process.
[0051] S2. Obtain the confidence of the large field weeding operation evaluation information according to the output weeding operation priority evaluation information , and at the same time set the credibility threshold of the weeding operation evaluation information , and calculate the weeding operation speed from the license plate recognition information, that is, the confidence of the license plate information , wherein, define the correction parameter value of the weeding operation speed ,
[0052] Define the first credibility threshold comparison parameter and the second credibility threshold comparison parameter of the weeding operation evaluation information, wherein, , compare the confidence of the weeding operation evaluation information with the first credibility threshold comparison parameter and the second credibility threshold comparison parameter respectively, and obtain the correction parameter value of the weeding operation speed according to the comparison result, , represents the standard weeding operation speed, and the specific process is as follows:
[0053] When the obtained confidence of the weeding operation evaluation information, the correction parameter value of the weeding operation speed is obtained as , ;
[0054] When the confidence level of the weed control operation evaluation information obtained , the weed control operation speed correction parameter value obtained is , ;

[0056] Among them, and respectively represent the influence coefficients of the confidence level on the weed control operation speed within the corresponding threshold intervals.
[0057] Among them, , the value for increasing the weed control operation speed. The system believes that the confidence level of the current weed control operation evaluation information is relatively high, but there is still room for improvement. For example, in the case where the weed coverage in the field is relatively good but there may be some minor interferences (such as environmental impacts), increasing the weed control operation speed can increase the chance of obtaining more accurate weed control efficiency, thereby improving the overall evaluation effect;
[0058] , the value for keeping the weed control operation speed unchanged, indicating that the confidence level of the weed control operation evaluation information is in a middle range. The system believes that the current weed control operation speed is appropriate and does not need to be adjusted. For example, when the weed coverage in the field basically meets the requirements but there is still some room for improvement, keeping the current weed control operation speed can continue to obtain the weed coverage for evaluation while avoiding system fluctuations caused by unnecessary weed control speed adjustments;
[0059] , the value for decreasing the weed control operation speed, meaning that the system believes that the confidence level of the current weed control operation evaluation information is relatively low. It may be due to abnormal vegetation index data or unstable meteorological information, resulting in a decrease in the confidence level. The system may reduce the speed of the weed control machine to reduce possible incorrect operations and ensure the accuracy of the operation.
[0060] At the same time, the original relationship between the confidence level of the weed control operation evaluation information and the weed control operation speed is: , represents a function, indicating the mapping relationship between the confidence level of the weed control operation evaluation information and the weed control operation speed ; Define the power consumption as , calculate the real-time weeding operation speed , represents the electric energy consumption regulation coefficient, and the specific process is as follows:
[0061] Among them, represents the first boundary; represents the second boundary; is within the normal range of electric energy consumption; represents a large electric energy consumption; represents a small electric energy consumption.
[0062] In the embodiment of the present invention, the measuring device records the weeding operation speed in the field and enters the preparatory work countdown. If the monitoring device detects a task of obtaining weeding machine information, it is in the preparation state, and the preparatory work countdown starts to count down. If the preparatory work countdown reaches zero, the work monitoring module enters the working state. If the monitoring device detects that there is no task of obtaining weeding machine information, the preparatory work countdown enters the initial start state. In the embodiment of the present invention, for example, the preparatory work countdown is set to 8 seconds. When a task of obtaining weeding machine information is detected, the preparatory work countdown starts to count down, such as: 8,..., 5,..., 3,..., 1..., when the value reaches zero, the work monitoring module enters the working state.
[0063] By considering the confidence level of the weeding operation evaluation information and the electric energy consumption situation, the present invention can adjust the weeding operation speed according to the situation, thereby improving the stability of the control system; dynamically adjusting the weeding operation speed can optimize the system performance, ensure more accurate weeding operation evaluation results under different electric energy consumption and evaluation situations, effectively save the use of control system resources, and avoid high-speed weeding operations and processing under unnecessary circumstances. At the same time, by dynamically controlling the working state of the device and only entering the preparation and working states when a task of obtaining weeding machine information is required, energy can be effectively saved; when there is no task, the device can enter the low-power initial start state to reduce unnecessary energy consumption; it can also improve the response speed of the system and ensure that the weeding machine information can be obtained in a timely manner when needed.
[0064] S3.

If the obtained determination index of the field weeding efficiency exceeds the threshold range of the weeding reference efficiency, it enters the working monitoring module, and at the same time, starts the preparatory work countdown. In the embodiments of the present invention, the calculation process of the determination index of the field weeding efficiency is as follows:
[0067] Wherein, represents the weight coefficient of the field weeding operation speed; represents the weight coefficient of the performance of the weeding equipment; represents the parameter of the field weeding operation speed; represents the parameter of the performance of the weeding equipment.
[0068] The specific judgment process is that there is a comparison parameter of the determination index of the field weeding efficiency inside the collaborative control module ;
[0069] When ≥ , the obtained determination index of the field weeding efficiency exceeds the threshold range of the weeding reference efficiency, starts the preparatory work countdown, and enters the working state;
[0070] When , the preparatory work countdown is not started. At the same time, the weeding efficiency compensation module starts to improve the operation speed and equipment performance information through the existing technologies known to those skilled in the art, such as: optimizing the operation path planning, adapting the maintenance frequency, etc.
